This invention relates to doors and particularly to door constructions and door operating mechanismsk for pier sheds and like structures.

In order to make full use of the space in Va pier shed or like structure, the cargo to Abe stored must be handled several times. For instance, the cargo is first deposited on the floor of the pier shed and is then piled up or stacked. This duplication of handling consumes time and adds to the expense of storing cargoes. 1

This invention has for its salient object to provide door structures and associated parts so constructed and arranged as to facilitate the unloading and stacking of cargoes in pier sheds or like building constructions.

Another object of the invention is to provide door closures and operating mechanisms therefor, so constructed and arranged and so operated that the doors when opened can be moved bodily away from the door opening to permit the direct stacking or piling of the cargo to a maximum height in the pier shed with-out additional handling.

Further objects of the invention will ap pear from the followingspecication taken in connection with the drawings, which form a part of this application, and in which Fig. 1 is a vertical, sectional elevation -through a pier shed illustrating door closures and operating mechanism therefor constructed in accordance with the invention;

The invention brieiiy described consists of the combination of a building structure, such as a pier shed, having a dooropening, a door closure therefor, and operatingmechanism for opening the door adapted to move the door to open position and thereaiterto move the door inwardly away from thev door opening or jamb. Theinvention preferably includes a carriage or. rameinto which the vdoor is moved when the door is operated to open position and means for moving the frame and door inwardly and to a slight degree upwardly away from the door opening or door jamb. The invention further provides a movable hatch cover or roo-f section and means for moving the hatch cover or roof section with the door frame and door inwardly away from the door jamb and upwardly whereby the cargo can .be swung into the pier shed through the opening in the roof, thus Jr'acilitating the piling or stacking of the cargo to the full maximum height in the pier shed without requiring more than one handling operation.

Further details of vthe invention will appear Jfrom the Afollowing description.

The pier shed or building structure in which the door closure and operating mechanism is embodied may be constructed in any desired manner'and it is commonin such structures to provide door openings and doors at both longitudinal lsides of the pier, as shown at A and B in Fig. 1. Portions of the side walls of the pier shed are shown at 10 and 11 in Figs. 5 and 6, the door jambs which bound the door openings being shown at 12 and 13. Angular frame structures 15 and 16 coact with the inner edges of the jambs 12 and 13 to form vertical guideways for receiving the door or door sections.

Tn the form of the invention illustrated, the door comprises a pair of door sections 2O and 21 which are movable vertically and lat erally to open position. The door sections may be hung or supported in any desired manner, and in the embodiment of the invention shown, the upper sections are hung or.

the chain or cable 76 drives the sheave 80. The shaft 97 is rotated by the rotation of sheave 8O and extends across the roof structure and has secured to its other end a sheave 80. The sheave 80 is connected by chain 76 to drive the sheave 82 at the left hand edge of the door opening, viewing Fig. 2.

It will be obvious that when the hand chain 85 is operated, the gearing operated by the hand chain will cause the sheaves 82 to be rotated, thus moving the cables 76 in the direction of the arrows shown in Fig. 7 and causing the arms 75 to move in an anti-clockwise direction. The movement of the arms 7 5 will rotate the shaft 7 3 and the arms 72 carried thereby, thus causing the links 7 O to lift the front edge of the hatch cover C to the position shown in Fig. 7.4

Further movement of the arms 7 5 is prevented by a stop 100. As the hand chain 85 is further operated, the movement of the cable 7' 6 in the direction of the arrow in Fig. 7 will cause the carriage or frame F and the hatch cover C to move upwardly and rearwardly to the position shown at the right in Fig. 1. During this movement the hatch cover C will be Jfree from the upper edge of the coaming and the front flan ge or edge of the cover will also be slightly elevated, thus eliminating friction. When the frame or carriage, door sections carried thereby, and hatch cover have been moved upwardly and rearwardly, the opening through which the cargo can be deposited in the pier shed will be materially increased, thus permitting the stacking of the cargo by one operation instead of by a plurality of operations.

Bsame of operation of door opening mecham'sm In order to cause the doors to open, the motor M is energized by the operation of a push button or any other desired form of switch. whereupon the door sections vwill be raised and swung inwardly to a position in which they are supported in the frame or carriage F. If it is then desired to unload a cargo into the pier shed. the hand chain 85 will be operated. causing the cables 76 to lift the hatch cover at the front end thereof and thereafter to move the carriage or frame F, door sections carried thereby, and cover upwardly and rearwardly to the position shown at the right in Fig. 1.

In order to close the doors and the parts associated therewith. the hand chain 85 is operated in the reverse direction and the movement of the Jframe and hatch cover from the position shown at the right in Fig. 1 to closed position is facilitated by the action of gravity since the tracks for supporting the frame and the rails for supporting the cover are inclined. The doors can then be closed by the reverse operation of the motor M, causing the cables 47 to unwind from vcntion is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:

1. In combination, a structure having a door opening, a hatch cover above said opening, hatch coamings for supporting said cover, a door for closing said door opening, means for opening said door, and means for successively raising the cover free of said coamings and moving the door and cover rearwardly of the door opening.

2. In combination, a structure having a door o-pening, a hatch cover above said opening, hatch coamings Jfor supporting said cover, a door for closing said door opening, means for opening said door, and means for successively raising the cover free of said combings and moving the door and cover upwardly and rearwardly of the door opening.

3. In combination, a structure having a door opening, a door "for closing the opening, rails, a carriage mounted on said rails, means for moving the door upwardly and rearwardly onto said carriage, means Jfor moving the carriage and door rearwardly on said rails, a movable hatch cover above the carriage, and operative connections between the carriage and hatch cover whereby the movement of the carriage will cause the cover to move rearwardly.

4. In combination, a structure having a door opening, a door Jfor closing said opening, a carriage, means for opening said door and moving the door to a position on said carriage, a hatch cover above the carriage, and means for moving the carriage and cover upwardly and rearwardly.
